HGL IOM Manual - Rev. B
HarmonicGuard
®
Low Capacitance
Introduction
Installation Guidelines
Mounting
The HGL must be mounted vertically on a smooth, solid surface, free from heat, dampness, and
condensation.
Wiring
Cable Entry Locations
The enclosed HGL filters are not provided with enclosure wiring knockouts. A location can be selected
at the time of installation. Typical or recommended cable entry locations are shown in the drawings
section of this manual.
Field Wiring Connection Terminals
Compression type terminals are provided for all field wiring connections. The wire size capacity ranges
and tightening torques for all field wiring connections are listed in the drawings and other information
shipped with the unit.
Grounding
The HGL panel equipment-grounding lug must be connected to the ground of the wiring system. The
equipment-grounding connection must conform to the requirements of the National Electrical Code
(NEC) and/or any other codes that apply to the installation site. The ground connection must be made
using a wire conductor. Metallic conduit is not a suitable grounding conductor. The integrity of all ground
connections should be periodically checked.
Power Wiring
Connect three-phase power of the appropriate voltage and current capacity to the circuit
protective device to the HGL input power terminals.
Note: in large units, the input power conductors are connected directly to the input terminals on
the line reactors.
Connect the output terminals of the HGL to the input power terminals of the VFD.
Note: in large units, the output power conductors are connected directly to the output terminals
on the line reactors. Refer to the VFD installation instructions for additional information.
Caution
Use copper wire that is appropriate for the voltage and current rating of the
equipment. The wire selection must conform to the requirements of the
National Electrical Code (NEC) and/or other applicable electrical codes.
For units rated less than 100 amps, use wire with an insulation temperature
rating of 60°C or higher.
For units rated 100 amps or more, use wire with an insulation temperature
rating of 75°C or higher.
